PDF/X-1a2001 image error auto fix, and add pdfx to smartphone

Hi, can you please ask Adobe to upgrade PDF/X-1a2001 software to automatically fix high and low resolution color, grayscale, and black and white images to 300 ppi, and line art to 600 ppi bit map, so that authors and creators are not required to search and change every image, and also because the error message does not indicate which specific images have errors, which could take vast amounts of time and energy to find and then upgrade or downgrade images. Also, please add PDF/X-1a2001 on Adobe mobile for smartphones. Thank you kindly.
